'Love for Alyssa': Examining arthrogryposisArthrogryposis has presented many challenges to Alyssa Jadyn Hagstrom. At just 8 years old, the condition has left her with no use of her legs and arms, and limited use of her fingers. Alyssa is the subject of photographer Jennifer Kaczmarek’s exhibition called “Love for Alyssa,” which aims to use photography, video and an online blog to raise funds for Alyssa’s and others’ medical needs. The project has put a spotlight on the little-known condition. Arthrogryposis causes limited range of motion in children’s joints and affects one in 3,000 infants, according to Donald Bae, an orthopedic surgeon at Boston Children’s Hospital.

It's true - you can practice in your sleepNorthwestern University researchers are validating procrasti-nappers everywhere – they say a 90-minute nap can actually help in learning a new skill. At least when that skill is remembering a musical tune. Participants in the study, published June 26 in the scientific journal Nature Neuroscience, learned two different musical sequences on a computer screen while watching moving circles that went along with them, similar to video games such as Guitar Hero and Dance Dance Revolution. After practicing for 25 minutes, the participants took a 90-minute nap. The researchers monitored the participants’ brain activity, and when they entered the “slow wave sleep stage” - a period of deep sleep with occasional intervening periods of REM sleep - the psychologists played one of the two sequences quietly.  Ryan can breathe on his own but has a tracheotomy tube so that his breathing isn't obstructed by his inability to swallow.

That was one year ago, and now Ryan — who is in a persistent vegetative state — is at home with his family. The Buchanans’ decision to keep Ryan at home (and alive) has polarized CNN commenters.
